Abstract

The invention discloses dispensing equipment, and further discloses a method for preparing a high thermal conducting interface material by adopting the dispensing equipment. The dispensing equipment comprises a dispensing die. The dispensing die is provided with a glue extruding channel. The glue extruding channel comprises a glue extruding channel inlet penetrating through the top surface of thedispensing die and a glue extruding channel outlet penetrating through the bottom surface of the dispensing die. The cross section area of the glue extruding channel decreases gradually from top to bottom. An included angle beta being 30-90 degrees is formed between the center axis of the glue extruding channel and a vertical line. The dispensing equipment has the characteristics that the structure is simple, the cost is low, and directional arrangement of carbon fiber can be achieved; the method can achieve directional arrangement of the carbon fiber, manufacturing of a large area of the highthermal conducting interface material can be achieved, and the high thermal conductivity interface material manufactured and obtained by adopting the method has excellent thermal conducting performance.

Description

technical field [0001] The invention relates to a glue dispensing equipment, in particular to a glue dispensing equipment and a method for preparing a high thermal conductivity interface material by using the glue dispensing equipment. Background technique [0002] The performance of electronic components will be degraded or damaged due to overheating, so the cooling of electronic components has become an important issue. For the thermal interface material used between the heating element and the radiator, it is often required to have excellent thermal conductivity. [0003] In the prior art, the invention patent with the publication number CN100548099C discloses a method for aligning carbon fibers by using a magnetic field. This method requires an ultra-high magnetic field strength (above 1T), and the equipment is difficult to manufacture and expensive. The environment is harsh and requires a non-magnetic environment to avoid accidental injury. The invention patent with t...
